A trusted brand for tyres
Upsizing tyres is a common trend. What it means is replacing the original tyre with a bigger tyre. In some cases, the wheel remains the same and in other cases, the wheels are also replaced and bigger wheels are used. Inch upsizing: This is where the wheels are replaced with bigger wheels. For example, replacing 15" Honda City wheels with 16" aftermarket wheels. In this case, both wheels and tyres have to be replaced.
Tyre Upsizing: In this case, we retain the original wheel size and only increase the contact patch of the tyre. For example, we can replace the stock 175/65-15 tyres on a Honda City to 195/60-15. There is a science to upsizing. The main concern while upsizing is to ensure the overall diameter or rolling circumference of the tyre is the same.
If the rim is upsized, the tyre has to give up a little bit of sidewall height to ensure the overall circumference remains as close to the original wheel and tyre. Have a look at our Tyre Size Calculator to see how you can safely upsize your car's tyres.
As a matter of policy, we do not advise any upsize which has a deviation of more than 2% from stock.
The sidewall of the tyre has a lot of text on it. Many of it is Greek and Latin to most consumers. Allow us to make it easier for you. The most important thing is the Tyre Size: If you see the sidewall of a Toyota Innova, you will notice the tyre size is 205/65 R15 94H.
205 refers to the width of the tread in millimetres. This is the contact patch of the tyre with the road. Typically, wider is better for grip. Of course, a wider tyre will also negatively impact fuel economy. 65 is the sidewall height. However, this is not an absolute number. It is a percentage of the tread width. In this case, 65 means the sidewall height is 65% of 205 mm which works out to 133.25mm.
The R refers to the fact that this is a Radial tyre and not a Nylon/Bias tyre. 15 refers to the diameter of the tyre.
There are also various other markings, the most important of which are the Load Rating and the Speed Rating. 94 refers to the load rating. It defines the maximum weight that can be borne by this tyre. A load rating of 94 means the tyre can take a maximum of 670 kgs on a single tyre. For a set of 4 tyres, this means the maximum weight of a car can be 2680 kgs. H refers to the Speed Rating. It defines the maximum speed at which this tyre can be used. An H Rating means the tyre is good for 210 kmph.
A link with a full list of load and speed ratings is listed below.
Wheel Alignment is the process of setting certain suspension angles to the OEM specification. These angles, like Toe, Caster and Camber can change over a period of time. Regular Wheel Alignment identifies mis-alignment and resets the angles to OEM specs.
Wheel Balancing is a process of measuring the imbalance of the tyre and wheel assembly and correcting it by adding weights directly opposite the heaviest point on the assembly. This eliminates only part of the vibration problems.
In today's modern cars, road force variation can also cause vibration which can cause excessive wear and tear of suspension components and in extreme cases can be felt while driving as well. The Hunter's Road Force Balancer has a load roller which applies a load on the tyre, simulating the real world road condition, and can help diagnose problems with either the tyre or the wheel. It helps diagnose issues faster without the need of a trial and error method.
The Hunter Road Force Balancer also checks the lateral (side to side) pulling of tyres and recommends the best possible locations for the set of 4 tyres. This eliminates another major problem with Wheel Balancing and Wheel Alignment as the car pulls to one side often due to the tyres. To eliminate this problem, the only solution is to try different positions for the set of 4 tyres, to find the best possible setting.
The Hunter Road Force Balancer ensures that a lot of time is saved and no trial and error is required. The video below explains why tyres and wheels can still vibrate or wobble even after Wheel Balancing is done.
Our Nitrogen machine produces 95% pure Nitrogen to fill your tyres. Normal air is 78% Nitrogen. The remaining 22% is made up of mainly oxygen and trace amounts of carbon dioxide, water vapour and other gases.
Oxygen and water vapour can cause rusting of the rim. Also, normal air expands with increase in heat. So running a car for extended periods of time can cause the tyre pressure to increase. In some cases this can be dangerous.
Nitrogen eliminates this problem. There is a negligible increase in tyre pressure with Nitrogen. Nitrogen molecules are also bigger than Oxygen molecules and this leads to one of the best advantages of Nitrogen inflation - longer gaps between topping up and checking air pressure.
The car's AC system has a refrigerant called R-134a which circulates inside the system and plays a primary role in chilling the outside air which is blown through the AC vents.
Over a period of time, the quantity of this refrigerant can reduce in the AC system. Our Texa AC Recharging systems sucks out whatever is left of the refrigerant, recycles it, checks for leaks and then refills the correct quantity of the AC refrigerant back into the AC system.
